To paraphrase Dostoevsky, one can measure the degree of civilization in a country by traveling its roads.
I learned this the hard way on a recent reporting trip to Finland. To catch my departing flight, first I had to rent a car to drive from Wilkes-Barre, Pennsylvania, to Newark airport. Then, en route, not only did I have to deal with the usual stress of having to balance the risk of getting a speeding ticket against the risk of getting into an accident by driving too slowly, I also got to meet some deranged hooligans straight out of “Mad Max.” Perhaps 15 or 20 souped-up cars and trucks, with deafening glass packs and side-dump exhausts, appeared suddenly around Stroudsburg, driving perhaps 100 miles per hour, weaving between lanes and onto the shoulder. One of them abruptly cut me off, nearly causing me to crash into another car.
It’s a familiar experience for anyone who drives, bikes, or walks on an American street. Hyper-vigilance is the natural response to roads filled with big, heavy, powerful cars and trucks driven at high speed, and often by people with a contemptuous disregard for anything but their own convenience and kicks.
So when I got to Finland to pick up a rental car, I was still amped. It’s a foreign country, and getting to my hotel meant I had to drive through the middle of the capital city. Surely this would be difficult.
It was not. I was surprised to learn that driving in downtown Helsinki is actually quite easy and safe — and later as I walked around the city, so is walking, cycling, or riding an electric scooter. What’s more, most of the road design policies that have made it so easy and safe to move around, drastically reducing carbon emissions in the process, are relatively simple. Even a sprawling American suburb could adopt most of them, with great effect.
The first and most important policy is to slow down traffic in towns and cities. Finland does have high-speed highways, but the speed limit only hits 120 kilometers per hour (about 75 miles per hour) far outside any settlement and only during the summer. Elsewhere, limits have been progressively reduced over the years. In the Helsinki suburbs, a limit of 80 kph, or 50 mph, is enforced with speed cameras. Further into the city, as the roads pick up more traffic and become more complex, the highway speed drops to 60 kph (37 mph), or even 50 kph (31 mph). On local city streets, the limit drops to 30 kph (18 mph), and most streets are narrow and paved with rough stone that, together with raised crosswalks, effectively force people to drive even slower.
A Finnish speeding ticket, which is levied as a percentage of one’s income, is no joke. Back in June, a wealthy businessman named Anders Wiklöf was fined 121,000 euros for doing 82 kph in a 50 kph zone. “I really regret the matter,” he told a local newspaper.
Thanks to those stiff and all-but-guaranteed fines, people hardly ever speed, and as a result, driving is much easier and safer. You’ve got plenty of time to change lanes, react to other cars, and figure out where you need to go. It’s actually rather pleasant. Without the white-knuckle American road culture, you can actually relax and enjoy the driving experience, even in the big city.
Low speeds are also central to pedestrian and cyclist safety on city streets. People are driving so slowly that even if someone darts right out in front of a driver, there is still usually enough time to stop. And if a collision does happen, lower speeds are exponentially safer for everyone involved. One study estimated that the risk of severe injury for a pedestrian struck by a vehicle at 26 kph (16 mph) was about 10 percent, but that increased to 90 percent at 74 kph (46 mph).
The second policy is to provide separate dedicated space for pedestrians, bikes, and public transit. Larger Helsinki streets typically have a sidewalk divided between a pedestrian section and a bike section, a lane for cars, and then a separated tram lane. This means less conflict between pedestrians, cyclists, drivers, and trams — and critically, the trams don’t get stuck in traffic. That means they can bypass any traffic congestion, and so those who don’t need or want to drive will logically opt to take public transit instead, thus letting the car lanes breathe. On smaller side streets, low speeds mean the city can forgo controls of any kind. Many Helsinki intersections don’t have so much as a stop sign; people just have to watch each other and negotiate on the fly — and it works.
Taken together, all this helps create a culture of walking, cycling, and transit use that is safer, healthier, and more efficient. Thanks to these reforms, Helsinki cut its annual pedestrian fatalities from 84 in 1965 to zero in 2019 (though there have been a couple in the subsequent years). Nationally, last year saw the lowest number of traffic deaths ever recorded. Meanwhile, cutting down on automobile trips is part of how Finland slashed its carbon dioxide emissions per capita by about half, from 14 metric tons in 2003 to 7 tons in 2021, as compared to 15 tons in America.
It’s also just more wholesome. Once it sunk in that I was about as safe as it is possible to be on a street, and didn’t have to be looking over my shoulder every few seconds to watch out for a careening 4-ton pickup truck, I felt the sense of peace that comes from releasing a worry that has been there for so long you’d forgotten what it was like to exist without it. Rather than being perceived as some irritating interloper getting in the way of drivers, I felt that I belonged on the street as much as anyone else. Conversely, I started viewing drivers, who invariably stop when anyone approaches a crosswalk, as fellow human beings rather than probable speed-crazed maniacs bent on running me down.
This safety no doubt helps explain why compared to an American city, one sees children on the street far more frequently in Helsinki; either big packs of young schoolchildren wearing high-visibility vests, shepherded by a couple adults, or kids from about seven and up out by themselves or in groups. And that’s despite the fact that the American birthrate is substantially higher than Finland’s. No doubt part of the reason for children being absent from the street is America’s hyper-neurotic parenting culture, but that culture is also fueled by the quite rational worry that unsupervised kids will be obliterated by a speeding lunatic.
It all sounds pretty fancy. But I want to emphasize that Helsinki is not really on the urbanist cutting edge. It still has some wide “stroads” here and there, and compared to, say, Amsterdam it is still relatively car-centric. But that also means that it isn’t too far off from the American city average.
Now, of course America couldn’t simply copy-paste every one of Finland road policies. We have neither the political will nor the administrative capacity to impose six-digit fines on rich jerks speeding through school zones in their Porsche Cayennes. It’s also hard to imagine the kind of stiff taxes on vehicle ownership and gasoline (about three dollars a gallon) that also makes driving much more expensive.
But we could have automatically enforced speed limits. New York City, for example, recently turned its (very limited) collection of speed cameras on continuously, after long delays from car-brained officials. Sure enough, speeding fell sharply along with traffic injuries and deaths of all kinds. We could also reclaim some road space for bike lanes and trams — or even just buses. The average suburban arterial has more than enough space, and e-bikes make many bike trips possible even in low-density sprawl.
Studies demonstrate that a substantial and growing fraction of Americans want to be able to live car-free. Another larger fraction would simply like the option to avoid driving if they don’t want to. The reason so many don’t is the risk. Make walking and cycling safe, and millions more will do it. We wouldn’t make it all the way to Finland’s level without the rest of its policies, but we’d get fairly far.
When reformers propose Finland-style changes to American cities, drivers commonly complain that it would cut into their freedom. But you can still drive just about anywhere in Finland, if you want to. Indeed, it’s much easier and safer to do so than it is in American cities. We have about the worst of all possible worlds, where we’re so dedicated to car supremacy that we’ve made our cities a dangerous, stressful, polluted hellscape even for drivers. There’s a better way.

The Iran war has been a gift to the country’s vehicle, solar, and battery business.
This is Heatmap Daily, a weekday evening digest written by our executive editor.
Happy Monday and welcome back. For months now, we’ve been talking about how the U.S. and Israel’s war in Iran has been a boon for electric vehicles, clean energy, and (unfortunately) coal.
But today we got data that confirms: This clean energy export boom is not just a side story. It is one of the brighter spots in the overall Chinese economy, which remains the world’s second largest.
According to economic data released on Monday, China grew 4.5% during the summer quarter as compared to the quarter from a year earlier. That means the country will likely hit its growth target this year, albeit on the low end.
The country’s economic expansion wasn’t driven by domestic consumption, however. Consumer confidence remains low, and residential investment has yet to return after the property crash earlier this decade.
Instead, booming exports are now driving China’s economy. Exports were more than 36% higher in September than a year earlier, driven by chips, ships, electric vehicles, and solar panels and batteries. The country will likely record its biggest trade surplus ever this year.
Some of those categories are clearly flourishing thanks to the global AI boom — think chips and even batteries. But the preponderance of vehicle exports suggests surging oil prices aren’t hurting. Sales of ‘new energy vehicles,’ a category that includes 100% electric vehicles and plug-in hybrids, were up more than 13% on a year-over-year basis in September, according to the Chinese car manufacturer’s trade group. But exports of these vehicles are booming. Battery electric vehicles were up 130% last month compared to the same period in 2025, and plug-in hybrid exports were up more than 200%.
It’s interesting to consider how much the Chinese and U.S. economy are mirroring each other at this moment. Americans are dealing with a remarkable investment boom, which is buoying the labor market and stubbornly maintaining high inflationary pressure. China is struggling with deflation, and exports are its quickest path to growth. (Consumer sentiment in both countries, interestingly, seems to be in the doldrums, even though American consumers appear to be in much better shape.)
When thinking about what artificial intelligence could do for the United States over the next decade, some subject-matter prognosticators (and even some Anthropic employees) imagine a world of 4%, 5%, or even 7% GDP growth. Such a growth rate is difficult even to envision in the modern era, of course, and it seems like it could propel the U.S. economy to staggering prosperity.
I know better than to make a prediction about where we’re headed. But amateur economic commentators should keep China in mind, too: a country that dominates along many technological axes, but where the standard economic math of supply, demand, and consumer sentiment still holds. Except if the United States economy were to stumble, no exterior source of demand will come to our rescue.
Endurance Energy hoped its generator would run for a full year, but the team isn’t afraid of the “error” in “trial and error.”
About 300 miles off the Oregon coast, a mile beneath the ocean’s surface, a startup just drilled the world’s first subsea geothermal well. And for a grand total of exactly 8.7 seconds, its prototype power plant generated about 2 kilowatts of net power. It wasn’t quite the result the Seattle-based Endurance Energy was hoping for — the company’s goal was to run its 100-kilowatt generator for a full year. But it’s not nothing.
“We really proved with this mission that a geothermal well could be drilled and completed on the seafloor, and doing that within 21 months of the company existing I think is really a testament to our pace of progress,” Endurance CEO Andrew Redd told me.
A former SpaceX engineer — as so many climate tech founders seem to be — Redd appears quite comfortable with the rapid trial-and-error cycles that hard tech startups often demand. Or as he stated in the company’s press release, which provides a refreshingly frank account of what this first test did and didn’t accomplish, “We follow the adage ‘make it exist, then make it good.’”
Investors seem to be buying it. In June, the startup raised a $54 million Series A, led by Peter Thiel’s Founders Fund — Endurance’s second funding round in less than two years of existence. Still, the team certainly has their work cut out for them. The ocean is a notoriously difficult operating environment: Saltwater is corrosive and offshore infrastructure is difficult and expensive to build, maintain, and repair.
Indeed, Endurance spent the first 11 days of its three-week stint at sea debugging its drill, which the team had never operated underwater before. But with a vessel chartered and a locked-in deployment date, the company couldn’t afford to wait for everything to work out perfectly. “We were still working on that generator hours before it got on the seafloor,” Redd told me. He’s used to that sort of thing, though, comparing it to making final tweaks to rockets already sitting on the launchpad. “That’s kind of the name of the game,” he said.
The trial took place at Axial Seamount, an active underwater volcano and the only place in the world with a cluster of hydrothermal vents connected to shore by fiber optic cable, which allows the Endurance team to monitor and control its system in real time from Seattle. While this was the company’s fifth deep-sea mission, it was the team’s first attempt to actually drill their own well.
After lowering their drill about a mile below the surface, the team bored two holes and turned the second into a well about 2 inches wide, lining it with pipe and sealing it with cement. But after losing so much time to debugging, the team only managed to drill about 52 feet deep — far short of its original 200-foot target.
Water then flowed up the well at about 260 degrees Celsius (around 500 degrees Fahrenheit), but the narrow borehole proved too restrictive to deliver enough heat for the generator to operate. So the team pivoted, connecting the generator directly to a naturally flowing, hotter hydrothermal vent instead. The generator then ran for a total of 29 seconds, producing about 2 kilowatts of net power for 8.7 seconds. That represents the total electricity the turbine generated, minus the 7 to 8 kilowatts needed to run its supporting components, such as the refrigerant pump and other onboard equipment.
Then a software glitch triggered the onboard battery safety system, which shut down the plant. When the team tried to restart the system, the power cable feeding the refrigerant pump failed, leaving the pump unable to restart. That was the end of the road. The mission wrapped up after three weeks at sea, a far shorter run than the team had hoped.
“The success criteria would be if we had left with the generator still on the seafloor; that would have been an example of sustained net power, and we didn’t get there,” Redd told me. Instead, the team brought the system back to Endurance’s Seattle headquarters, where it’s fixing the software as well as refurbishing and upgrading the hardware — which includes changing how it builds and tests subsea cables — to prepare for another mission sometime this winter. This time, the goal will be to generate sustained power from a much deeper well.
The team will need to demonstrate progress soon to keep its next major milestone on track: a planned 2-megawatt deployment off the coast of Tonga by the end of 2027. The project aims to supply electricity directly to the Tongan grid, which today is heavily dependent on expensive, imported diesel. Redd expects subsea geothermal to be cost-competitive with that fuel in this first pilot.
Getting there, however, is a formidable engineering challenge. While it’s long been a subject of academic curiosity, no one prior to Endurance had ever drilled an offshore geothermal well before, meaning the team can’t simply transplant existing land-based technology to the seafloor. “Every component that you would use terrestrially now needs to be either modified or built completely from scratch,” Redd explained. “And so you multiply that across every component required to make these kinds of infrastructure projects happen, and it’s a lot of work.”
No kidding. But if Endurance can pull it off, Redd sees this resource as “the perfect energy source for the future.” A conference paper presented by the geoscience company Viridien last year estimates that offshore geothermal resources worldwide could yield about 6 terawatts of recoverable electric power — nearly twice the world’s current continuous electricity output.
“We can access terawatts of power. There’s no fuel. We can site next to extremely large cities around the Pacific. We have no surface presence,” Redd said, ticking off the advantages. Plus, the three necessary ingredients for a high-quality geothermal well — permeable rock, high heat, and water — are widely accessible offshore, he added. Eventually, he expects subsea geothermal to undercut natural gas in Endurance’s target markets: electricity grids, industrial facilities, and data centers across the Pacific Islands, the U.S. West Coast, and Northeast Asia, all of which sit along the undersea volcanic zone known as the “Ring of Fire.”
The way Redd sees it, advances in subsea technology pioneered by the offshore wind, oil, and gas industries have cleared much of the technological path to making underwater geothermal a viable clean energy resource. In his view, what’s been missing is simply the ambition to chase the opportunity in the private market. SpaceX, he said, really proved what’s possible for a scrappy startup to achieve.
“It is quite new at industrial scale for a small company with a bunch of fairly young people to go after something like this,” he told me. “Before SpaceX went to launch a rocket as a private company, no one thought you could get to orbit as a private company. And so that has really seeded this ambition.”
On Greenland’s deepsea mining ban, Indonesia floating nuclear, and a solar boom
Current conditions: Hurricane Trudy has weakened from its peak as a Category 2 storm but still threatens up to 8 inches of rain as it swirls off Baja California • A nor’easter is howling through the Mid-Atlantic this week, hammering the coast with winds of up to 70 miles per hour • A humid overcast has settled over Paris this week as French authorities struggle to regain control after protests over living costs gave way to anarchic riots.
At least 47 major data center projects have been delayed, withdrawn, or blocked so far this year, according to data the regulatory intelligence service RegLayer shared with the Financial Times — and that may be a “conservative estimate.” Just 35% of planned data centers are “credible,” analysts told the newspaper, as more than 1,000 communities across the United States now have restrictions on artificial intelligence infrastructure. The data comes as investors look increasingly jittery about AI following ChatGPT-maker OpenAI’s missing a key revenue metric this year.
Those findings stand in contrast with the numbers from our data service, Heatmap Pro. Based on our research, at least 107 projects faced cancellation so far this year, putting 2026 on track to beat last year, which saw 108 proposals nixed.
Unless you’re living off the grid and away from any social media (if so, I’m jealous), then you can probably surmise that not-in-my-backyard opposition prevails in many such cases against proposed data centers. That makes selling would-be neighbors on the projects critical. New polling by the advocacy group GoodPower found that a binding promise to protect local electricity rates boosts support for the projects upward by as much as 14 points. Such a pledge worked primarily on the 78% of voters who distrust data centers. Another potential winner: Pair a data center with renewables. At least 46% of respondents to the poll said their support would increase if a project were powered by renewables. The survey spoke to 2,610 registered voters last month and oversampled in states with at least 200 data centers completed: Arizona, Georgia, Indiana, Pennsylvania, Texas, and Virginia.
Greenland wants to find ways to exploit its mineral riches in hopes of generating enough income from industries other than fishing and tourism to eventually wean off subsidies from the governments of Denmark and the European Union. Earlier this month, as you may recall, the self-governing Danish island gave a project the green light. But the government in Nuuk doesn’t want miners harvesting metals from the seabed surrounding the Arctic island, which are fertile fishing grounds and could, in theory, lead to mineral production without meaningful infrastructure to create jobs for Greenlandic people. Last week, the Greenlandic Parliament adopted a resolution requiring the government to draft legislation banning deep-sea mining. All members present voted to approve the proposal, according to Sermitsiaq, a leading newspaper in Nuuk. The ban would, if adopted, last until the end of 2029, with the possibility of an extension for two years at a time.

Long before the race for small modular reactors kicked off, Russia launched a floating nuclear power station and sailed the vessel up to the Arctic to power a small town. Now, as you may recall, the state-owned Russian nuclear company Rosatom is making plans to build more floating nuclear plants, and it has a major nuclear newcomer nation as an offtaker. Last week, NucNet reported, Rosatom announced a deal with Indonesia’s state-owned PT Pembangkit Listrik Nuklir to supply electricity to northern Indonesia from at least two floating nuclear plants with a capacity of 200 megawatts each.

Over the past decade, small-scale and rooftop solar systems increased from 18,812 gigawatt-hours to 92,979 gigawatt-hours, an increase of over 394%. That’s according to a new analysis from the Energy Information Administration, which found that California, Arizona, Texas, Florida are the regions with the most abundant solar resources. Even though the state has worse solar resources in general, New York ranked fifth as a result of growing capacity. Still, the rate of growth in generation has slowed over the past three years. l
The Trump administration is pulling out all the stops for Alaskans who want to drill and transport fossil fuels, mine minerals, and log trees. Now he’s easing rules on hunters. A new final rule from the National Park Service has revived a hunting method the Biden administration banned in 2024: Baiting bears with doughnuts soaked in bacon grease. Hunters use the baits to lure bears to close range before shooting them. “Some hunters prefer to use strong-smelling, high-calorie foods like pastries, doughnuts, meat scraps or fish remains to lure bears from miles away,” The New York Times reported. “But some conservationists say the practice is unethical and risks making the bears accustomed to human food, which could endanger people.”
